GANoPY-FRAME.

SPECIFICATION forming part of LettersPatent No. 255,093, dated March 14, 1882.

Application filed August 9, 1881. (No model.)

To all whom it may' concern.-

Beit known that I, GHARLEs WITTENBERG, a citizen ofthe United States, residing at Indianapolis, in the county ot' Marion and State of Indiana, have invented a new und useful Improvement in Folding Extension Hanging Canopy-Frames, of which the following is a specification.

My invention relates to improvements in hanging canopy-frames in which the frame is made to fold up or be extended,as desired and the object of my invention is to provide a han ging canopy-frame which may be extended to spread the canopy over a bed or folded up out of the way. This object I accomplish by the device illustrated in the accompanying drawings, in which- VAFigure l represents a perspective view of a canopy-frame extended, with the canopy attached thereto. Fig. 2 is a plan view of the canopy-frame extended, and Fig. 3 represents the canopy-frame folded up.-

4Similar letters refer to like parts throughout the several views.

A and B represent the two main bars ot' the canopy-frame, pivoted together in their center by a bolt and thumb-nut, G. The' short bars G D are pivoted together at d, and the other ends of the bars C D are pivoted at e c to one end of the main bars A B. In like manner the short bars E F are pivoted together at a and to the other ends ofthe bars A B at b f. The extreme ends of the main bars A B are also united together by the cords g g', the length of which limit the extension ofthe frame. The cords g g' also are secured to the edges of the bars O D E F. To these cords g g and the short bars `C D E F the canopy-frame is attached, the upper end of the canopy being gathered together above the frame and provided with a loop, H, for suspending it from the ceiling.

When it is not desired to use the canopy' frame it is folded up, as in Fig. 3.

What I claim as new, and desi/re to secure by Letters Patent, is

The two bars A B, pvoted together in the center by the pivot Gr, andhaving the short bars O D E F pivoted to their ends, combined with the cords g g', adapt-ed to be extended or folded up, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two sub. scribing witnesses.
